"Does exposure to blue light before bed decrease sleep quality by 30%?
Blue light emitted from smartphones, tablets, and computers suppresses melatonin production, making it harder to fall asleep.
Prolonged blue light exposure can lead to chronic sleep deprivation and related health issues.
What's your bedtime routine to avoid the blue light sleep killer?

Big Picture Science for June 29, 2026: Skeptic Check: Blue Light Special
Many of us know the feeling: we intend to go to bed but pull out our phones for one last scroll. Setting them aside hours later, we’re wide awake, unable to fall asleep. For years, scientists have singled out blue light emitted from our devices as the key culprit behind our post-scrolling insomnia, but the scientific consensus is shifting. Although blue light signals to brains that its daytime, surprising new research suggests that our glowing screens may play a smaller role than previously thought.
We present the fascinating science around biological mechanisms of sleep and wakefulness, why circadian rhythms have more in common with your grandfather’s clock than you might think, and why scientists who question the role of blue light in causing nighttime restlessness, still don’t let our phones off the hook completely.
Guests:
* Michael Gradisar – clinical psychologist and sleep researcher, former professor at Flinders University in Australia. Currently serves a head of Sleep Science at Sleep Cycle, a sleep tracking app company
* Jay Dunlap – geneticist and molecular geneticist at the Geisel School of Medicine at Dartmouth who works the molecular basis of circadian rhythms
* Mariana Figueiro – photobiologist, Director of the Light and Health Research Center and Professor of Population Health Science and Policy at the Icahn School of Medicine at Mount SinaiDownload podcast at - https://bigpicturescience.org/episodes/skeptic-check-blue-light-special

"Do you know using screens before bed can cut sleep by 45%?"
Exposure to blue light from smartphones, tablets, and computers tricks the brain into thinking it's still daytime, suppressing melatonin production.
This disrupts the body's natural sleep-wake cycle.
"Sleep is the best meditation," says Dalai Lama. Can you meditate before bed without screens?

"Is exposure to blue light before bed reducing your sleep quality by 60%?
Prolonged exposure to blue light, emitted by smartphones, computers, and TVs, suppresses melatonin production, making it harder to fall asleep. This is because blue light tricks the brain into thinking it's still daytime.
A good night's sleep is just as vital as a meal, it's not a luxury, it's a necessity.
What do you do to avoid the blue light sleep killer?
